Application, December 15, 1932 Serial No. 647,314

3 Claims.

This invention relates to water closet bowl construction; more particularly, to clean-out means therefor.

My invention is directed to Water closet bowl construction and clean-out means therefor, particularly such water closet bowls generally referred to as siphon bowls, in which the bowl proper has an exit end connected through a siphoning channel, thereby normally providing a water seal for thebowl. In this type of construction, the upwardly directed'leg of the siphon which is subjected to the evacuating and propulsive action of water forms a source .of considerable annoyance as it isthe point at which cloggingwill most frequently occur from solid materials which may be deposited accidently or indiscriminately in the bowl.

In a water closet bowl of the character re- -O ferred to, the upper leg of the siphon of this 2 type of bowl construction is most usually formed with a wall integral with the interior of the bowl and, this is most frequently rearwardly disposed, and adjacent the source of the water supply,

(25: where'excrement deposited upon thiswall may be 'most readily washed away and cleansed. This arrangement of the bowl, its siphon construction "and complementalparts, has; further been the source of causing the closet bowl to falleasily into disrepair, by reason of the inaccessibility of the parts, making proper maintenance expensive, asthe bowlwould be removedfrom the base to which it is cemented to effect repairs.

By constructions as known to me, the provision r of clean-out means for one of the siphon legs from exterior points of the bowl construction and through the exterior walls are objectionable and inadequate in that they are either inaccessible, where the vertical siphon leg is directed adjacent the'water supply, or, if disposed away from, the water'supply' and disposed through the exterior wallof the bowl, upkeep is difiicult and expensive by reason 'of the parts forming the clean-out structure being constantly subjected to the corrosive action of liquids, gases and solids. Additionally, at times when repair is necessary, cleanout means connected with the exterior wall of the bowl require special attention to the extent that at the'time that replacement or repair is made, not only is there a quantity of liquid present which ordinarily provides the water, seal for the siphon, but a considerable amount in excess thereof, which has failed to be discharged, and which forms a substantial fluid head to the cleanout opening. 7

It is therefore an object of my invention to provide a water closet bowl construction which includes an over-flowsiphon interposed between the exit end of the bowl and the exit drain line, and to associate with said siphon, means to clean out a branch of said siphon, which are readily 6O accessible and. which will be retained in condition, requiring minimum attention and repair.

It is further an object of my invention to provide a closet bowl'construction of continuous contour, characteristic of an integral construction on its exterior from the entrance end and water supply, to the exit end, and having an interposed siphon serving as a. water seal, the siphon including a readily accessible interiorly disposed cleanout member whereby one branch of the siphon 7 may be reached for purposes of freeing the same from obstruction and all operations therefor confined and performed from the interior of the bowl.

It is a further object of my invention to provide in a closet bowl which includes an integrally formed siphon Water seal disposed adjacent the water supply for said closet, of clean-out means disposed interiorly of. said bowl, to render one branch of said siphon accessible, such clean-out means being all disposed interiorly of the bowl, avoiding. thenecessity of providing closure elements exposed to the exterior of the bowl.

'It is still further contemplated as an object of my invention to provide in a closet bowl construction including a siphon drain forming a water seal for the bowland including a clean-out member and construction features therefondisposed in relation to said water seal and of such construction, facilitating access for repair and main-,

tenance, by being disposed above the normal level of the water seal, during normal and proper operation. It is further contemplated by me tov provide a clean-out member 'of such construction and location which will not interfere with the sanitary, clean and innocuous maintainance of a water closet bowl.

Other objects of my invention reside inthe provision of a closet bowl construction having a siphoning means serving as a water seal and the provision, of a clean-out construction therefor, which is inexpensive to install and maintain and replace. j

To'attain these objects andsuch further objects as may appear herein or be hereinafter pointed out, I make reference to the accompanying drawing, forming a part hereof, in which- Figure l'is a vertical sectional view of a closet bowl disclosingone embodiment of my invention; r

Figure 2 is a fragmentary, enlarged frontal elevation of an interior wall of the bowl;

Figure 3 is a section taken on the line 3-3 of Figure 2;

Figure 4 is a view similar to Figure 3, showing another embodiment of my invention.

Making reference to the drawing, 1 have illustrated the same in connection with a water closet bowl 10, generally made of crockery, porcelain or enameled metal. The bowl includes a pedestal l1, integral therewith, serving to support the bowl upon the floor adjacent a drain pipe over which it maybe cemented in the usual way. The seat supporting or entrance opening 12 is of the usual construction, including a water conducting channel 13, supplied from the opening 14, which isadapted to be connected with the water supply line (not shown). Water maybe discharged circumferentially from the channel 13, but prima rily from the opening 15, directed downwardly over an apron or wall 16 integral with the bowl proper and its exterior walls. This wall cooper-' ates with an upwardly directed wall 17, forming the upper branch or outlet 18 of a siphon drain 19. The lower or downwardly directed branch 20 leads to the exit or discharge outlet 21, adapted to be connected as previously described, to the drain pipe or line. Connected with the siphon 19, at a point well above the upperpoint 22 of the wall 1'7, there is formed in the wall or apron 16, an orifice 23. This may be drilled or tapped for receiving a collar 24, shown in greater detail in Figures 2 and 3. The collar is preferably also interiorly threaded for receiving a closure or plug 25. This member is preferably formed with an enlarged head 26, adapted to cooperate with the seat 2'7, formed into the collar 24. Formed in the enlarged head 26, a convenient slot' 28 is provided, adapted to be engaged by a suitable ,tool, such as a screw driver for rotating the closure or plug. i

It will be understood that with the construction as provided, the bowl may be disposed with the water supph connection 14 adjacent the wall,

' and thereby also similarly positioning the siphon discharge portion thereof.

In use, should any obstruction occurin the leg 18 of the siphon, the'closure or plug 25, may be removed and in this condition, thus renders either branch of the siphon l9 readily accessible, whereby some convenient tool, such as a wire, may be used-to relieve the obstruction. Under ordinary conditions, removal of'the' plug or closure 25 is sufiicient to of itself, relieve the obstruction, as this will not only reduce the diminished pressure head holding the obstruction in position, but may also accomplish a relief of this condition by the rush of water through theorifice 23 todisplace the obstruction. I

By disposing'the orifice 23 at the point described in its normal use, thelbushing and closure therefor are disposed above the normal water level maintained within the bowl, thereby maintaining the bushing and its closure in condition exposing the same to minimum erosion, but with maximum cleanliness. Furthermore, this part may be easily and conveniently reached for purposes of removing the plug or closure for the insertion of a wire water hose or similar tool, to clean'out any ob-,

struction in the branch 18 of the siphon. Should any obstruction occur, preventing water from leaving the bowl 18 and causing the same to rise as far as the edge 12, removal of the plug will immediately discharge a'large percentage of the contents of the bowl through the orifice 28 and out tates the relief of the obstruction which may be on the leg 18. Thereafter, the branch 18 of the siphon may be freed of the obstruction and the bowl restored to its usual operation. Furthermore, it will be observed that by location of the orifice at the point noted, the metallic parts may be employed for the closure in the form of the bushing or collar 24 and any erosion influence will not render the entire construction inoperative, by reason of this action, as any leaks which may be caused therebywill not be objectionable and the fluid will still be retained within the bowl.

I further consider novelty to reside in the form of the construction which the bushing or collar and its closure make with the wall into which the: parts are mounted, whereby a smooth and continuous surface is provided for the wall 16, exteriorly and interiorly thereof, thus avoiding the accumulation of any excrement or debris and forming a readily cleansible and sanitary construction.

In another embodiment ofmy invention, as more particularly shown in Figure 4, I have illustrated a clean-out orifice which may readily be installed upon existing constructions. In this embodiment of my invention, the wall 16 may be provided with an orifice 23a, preferably forming tapered walls, by drilling, boring or forming this orifice in the original casting of the bowl. In this form of construction, I provide a collar 24a, whose exterior walls make complemental engagement with the orifice 23a. This collar may be made of metal or non-corrosive material, such as hard rubber, bakelite or the like. The wall of the orifice 23a,

, and the exterior wall of the collar 24a are proand thereafter the collar 24a is forced in position within the orifice 23a. The colla'r'24a. is provided for a short length thereof, with an internal threaded section 31, adjacent the restrictedopening. The enlarged opening is provided with a. tapered seat 32. Within the collar, there may be positioned a'closure or plug 33, having a short external threaded section 34, arranged to cooperate with the threaded section 31 of the collar 24d. The plug is formed with an enlarged head3L5', arranged to bear upon theseat 32. A restricted neck or 'shanl; 36 is disposed between the threaded pore tion 34 and the head '35. The head 35 may be formed with a slot or kerf 37, adapted to be en:- gaged by some operating tool, such as a screw driver. I

The construction just described not only perimits of my device being installed in existing water closet bowls, without the necessity of removal thereof, simply by providing a drilling in the wall 1 6, but when so installed, removal and replacement may be. conveniently made, as the plug provides minimum friction for rotation, at the same time exposing smooth and easily cleansed surfacesto either side of the wall 16.

This application is a substitute in part for my abandonedapplication, Serial No. 546,898. Having thus described my invention and illustratedits use, what I claim as new and desire to secure by Letters Patent, is- I c l. A water closet bowl having a siphon dis: charge leg leading from a lateral opening in the bowl, and an interiorly disposed, inwardly rected substantially vertically disposed skirt or wall extending towards the bottom of said bowl, forming a continuous discharge passage from said bowl through said opening, a water supply inlet for said bowl adjacent said siphon, adapted to discharge a supply of water over said skirt or wall, an orifice formed in said skirt or wall adjacent said lateral opening at a point above the normal level of the water seal formed by said siphon, and a removable closure for said orifice, said removable closure being formed to engage saidorifice and of a thickness substantially equivalent to said'wall to make smooth and continuous contact with the opposite surfaces of said skirt or wall.

2. A water closet bowl including a laterally positioned discharge opening spaced intermediate the bottom and entrance end of the bowl, a channel for said opening forming a discharge pipe below the bottom of said bowl, an interiorly directed substantially vertically disposed skirt or wall integrally formed and spaced from said bowl for a portion thereof, extending over said opening toward the bottom of said bowl and forming with a portion of said bowl the upper leg of a discharge siphon and water seal, and an orifice disposed in said skirt or wall whereby said upper leg is made accessible from the interior of said bowl, and a closure for said orifice, mechanically sealing the same and engaging the walls thereof forming a smooth and continuous surface on the interior and exterior surfaces of said interiorly directed skirt or wall.

3. A water closet bowl having a siphon discharge leg leading from a lateral opening in the bowl, an interiorly disposed, inwardly directed substantially vertically disposed skirt or wall extending towards the bottom of said bowl forming a continuous discharge passage from said bowl through said opening, a water supply inlet for said bowl adjacent said siphon and skirt or wall, adapted to discharge a supply of water over said skirt or wall, an orifice formed in said skirt or wall adjacent said lateral opening at a point above the normal level of the water seal formed by said siphon, a collar disposed within said orifice having interlocking means with said wall, said collar having a partially'threaded section and including a seat, and a plug having a spaced threaded section and head, engaging said threaded section and seat, respectively, of said collar, forming a readily removable closure for said orifice, mechanically sealing the same and engaging the V walls thereof forming a smooth and continuous surface on the interior and exterior surfaces of said interiorly directed skirt or Wall.
